# 
# The
# 	make x
# 
# command should therefore generate two lines:
# 
# 	Hello,
# 	World
# 
# with no error on a 'make' command that is POSIX-compliant.
# 
# The
# 	make -n plus
# 
# command should print
# 
# 	echo a command
# 	echo "a command prefixed by '+' executes even with -n"
# 	a command prefixed by '+' executes even with -n
# 	echo another command
# 
# to show that it is not executing the first and last echo command, but
# is executing the middle one.
# 
# The
# 	make err
# 
# command should print
# 
# 	Now we expect an error...
# 
# and exit with an error code 1.
# 
# Running all of the tests may require adding a few command-line
# arguments if the paricular version of make does not support setting
# the .MAKE or MAKEFILE macros such as this:
# 
# 	make .MAKE=/usr/bin/make MAKEFILE=Makefile
# 


#
# Note that an action which consists of a more complex shell command,
# such as one using a loop, and maybe also one which uses a
# conditional command, should explicitly use 'set -e', if desired, to
# ensure that errors during a sub-command are detected immediately.
